Alarm Phone also tweeted its concerns, saying it had received a call from the boat, which departed from Tobruk in Libya.

The captain has left and there is “nobody who can steer the boat”, Alarm Phone said.
It added that it had alerted the authorities.

There has been a rise in the number of migrant boats crossing the Mediterranean from North Africa recently, Reuters reported.
Another NGO, Germany’s Resqship, said on Sunday that at least 23 migrants died overnight in the Mediterranean in a separate shipwreck.
It tweeted that it found 25 people in the water during a rescue operation.
Last week, 440 migrants were rescued off Malta after a complex 11-hour operation in stormy seas by the Geo Barents
vessel of the Doctors Without Borders (MSF) charity.
